Hey!
I often need to import part of a video in TVP, but choosing the mark in/out is a little difficulte. You can't increment/decrement the number with arrows so you have to write the number each time to check the image, and when you click enter you lose the controle on writing on the box. So I end up clicking, changing the number, enter... Clicking again, changing the number, enter... Etc.
A little slider to flip image after image, two buttons + arrows shortcut to go frame by frame and staying on text mode while hitting enter could be the easiest workaround.

As I'm highly interested in animation workflows, I'm open to scripting new TVP functions for individuals and studios. Please don't hesitate to contact me!
